Description
(a) ポリマーシェル;及び
(b) 25℃超の融点を有する農薬を含むコアであって、当該農薬が25℃以上の融点を有するが、ガラス転移温度を示さない疎水性材料中に固体として分散することを特徴するコアを含むマイクロカプセルを含んで成る製品に関する。
ステップ1−固体水溶性の生物学的に活性である化合物を粉砕工程によって適切に要求される粒子径で生産する。固体の適切な体積中央粒子径(VMD)は0.01〜50μmであり;より適切には下限が0.5μmであり、またさらにより適切には下限が1.Oμmであり;より適切には上限が10μmであり、またより適切には上限が5μmである。
ステップ1−固体農薬を粉砕工程によって適切に要求される粒子径で生産する。固体の適切な体積中央粒子径(VMD)は0.01〜50μmであり;より適切には下限が0.5μmであり、またさらにより適切には下限が1.Oμmであり;より適切には上限が10μmであり、またより適切には上限が5μmである。
(i)アミン対イソシアネート部分が約0.8:1〜約1.3:1の範囲のモル比を有する、およそ当モル濃度のアミンとイソシアネート部分が採用され、この場合における壁形成反応は、適切には疎水性固体の融点を超える温度で、または独立した冷却ステップの場合は、約20℃〜約40℃、さらにより好適には約20℃〜約30℃の疎水性固体の融点を下回る温度に下げる工程に導入されて実施される;或いは
(ii)アミン対イソシアネート部分が約0.1:1〜約0.35:1の範囲の比率を有する、有意な過剰のイソシアネートが存在し、この場合における壁形成反応は、好適には約30℃〜約60℃、さらにより好適には約40℃〜約5O℃の温度で実施される。
(i) 疎水性材料を融解して、疎水性液体を形成し;
(ii) 当該疎水性液体中に農薬を分散し;
(iii) 水性相中に当該疎水性液体を乳化し;
(iv) 任意に得られたエマルションを冷却し;
(v) 疎水性液体と水性相の間の界面で界面重合反応を引き起こし、カプセル懸濁物を生産し;そして
(vi) 任意に当該カプセル懸濁物を冷却しまたは冷却を引き起こすことを含んで成る、本明細書において発表されたような製品の製造方法を提供する。
(a) ポリマーシェル;及び
(b) 25℃超の融点を有する農薬を含むコアであって、当該農薬が25℃以上の融点を有するがガラス転移温度を示さない疎水性材料中に固体として分散することを特徴するコアを含むマイクロカプセルを含んで成る製品に関する。
以下の実施例は、チアメトキサムが融解可能な疎水性固体中に懸濁され、その後にポリ尿素壁中にカプセル化され得ることを実証する。ここでポリ尿素壁を形成するためのイソシアネート部分は、融解可能な疎水性固体中に溶解される。かかる製剤は、高い水溶性のチアメトキサム(20℃で4.1g/l)を成功裏に調製するためには些細なものではない。これはチアメトキサムの粒子が乳化工程の間に、及び/または融解可能な疎水性固体が固化する前に水性相中に移動して、マイクロカプセル壁の形成が完成する傾向があることを意味する。チアメトキサム粒子の水性相への過剰な移動を予防することは、乳化工程において上昇した温度が採用されることに起因して、本製剤タイプについて特に試みられている。
